TANGO1

TANGO1 is a membrane-associated protein that plays a crucial role in the regulation of cellular processes such as endocytosis, cell signaling, and the maintenance of cellular homeostasis. Its name is derived from the T-cell activation gene 1, but it has since been recognized to be a distinct protein.

Research has shown that TANGO1 is involved in the formation of an ER-PM tether, which is a complex structure that connects the endoplasmic reticulum (ER) to the plasma membrane (PM) in cells. This tether is essential for the proper functioning of cells and the maintenance of their homeostasis. TANGO1 is a key component of this ER-PM tether and is necessary for its stability.

Studies have also found that TANGO1 has a role in regulating the endocytic pathway. It is involved in the recruitment of ESCRT-III components to the endosomal membrane, which is necessary for the sorting and processing of proteins and lipids in the cell. TANGO1's role in the endocytic pathway suggests that it may play a role in various cellular processes, including cell signaling and the response to external stimuli.

While the specific functions of TANGO1 are still being studied, its role in the ER-PM tether and the endocytic pathway suggests that it is a critical component of cellular processes. Further research is necessary to fully understand the functions and regulation of TANGO1.
